Sub-1 GHz RF communication software expansion for STM32Cube

X-CUBE-SUBG1 is an expansion software package for STM32Cube. The software runs on the STM32 and includes drivers that recognize the Sub-1 GHz RF communication for SPIRIT1 modules SPSGRF (SPSGRF-868 or SPSGRF-915). The expansion is built on STM32Cube software technology to ease portability across different STM32 microcontrollers. The software comes with examples of implementation of P2P, wM-Bus and 6LoWPAN communication protocols, running on a SPIRIT1 module SPSGRF expansion board (X-NUCLEO-IDS01A4 or X-NUCLEO-IDS01A5) when connected to a NUCLEO-F401RE or NUCLEO-L053R8 or NUCLEO-L152RE. wM-Bus communication protocol is available for X-NUCLEO-IDS01A4 only.

Key Features

  • Firmware package to kick-start development using SPIRIT1 expansion boards
  • Complete middleware to build wireless meter bus (wM-Bus) applications using the wM-Bus library (X-NUCLEO-IDS01A4 only)
  • Middleware library with Contiki OS and Contiki 6LoWPAN protocol stack 3.x (NUCLEO-F401RE and NUCLEO-L152RE only)
  • Sample point-to-point communication application for simple buffer transmit and acknowledgement implementation
  • Low-power optimizations for the STM32 MCU family
  • Easy portability across different MCU families thanks to STM32Cube architecture
  • PC-based application (Windows® ) for wM-Bus to log meter data
  • Free user-friendly license terms
  • Sample implementation available on board X-NUCLEO-IDS01A4 or X-NUCLEO-IDS01A5 when connected to NUCLEO-F401RE or NUCLEO-L053R8 or NUCLEO-L152RE
